Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If task preemption is allowed in vehicle systems, then system responsiveness and priority handling are improved, but data synchronization between tasks deteriorates
Solution Approach 1:
The patent applies preliminary action by generating software agents in advance that automatically manage task synchronization. These agents are created before runtime based on DBC file analysis, and they proactively monitor and coordinate data exchanges between preempted and non-preempted tasks, ensuring synchronization is maintained without requiring real-time intervention during task preemption events.
Solution Approach 2:
The patent introduces software agents as intermediary components that mediate between different tasks in the vehicle system. These agents act as intermediaries that receive data from source tasks, validate and transform it according to DBC specifications, and deliver it to target tasks, thereby ensuring data synchronization even when tasks are preempted by higher-priority operations.
2Reliability
If end-to-end checking is performed to ensure data correspondence, then data accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies self-service by implementing automated software agents that autonomously perform end-to-end data checking and validation. These agents automatically read DBC files to understand data specifications, monitor data flows between tasks, verify data correspondence, and generate reports without requiring manual configuration or intervention, thereby reducing system complexity while maintaining high data accuracy.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting validation thresholds and checking frequencies based on DBC file specifications. The software agents adapt their behavior according to the specific data types, transmission intervals, and validation requirements defined in the DBC files, allowing the system to maintain appropriate data accuracy without uniform complex checking across all data streams.
3Reliability
If software agents are generated to manage synchronization, then data correspondence is improved, but processing overhead increases
Solution Approach 1:
The patent applies partial action by implementing selective software agent deployment that focuses validation and synchronization efforts only on critical data streams and high-priority tasks. The system analyzes DBC files to identify which data exchanges require stringent synchronization and allocates software agent resources accordingly, avoiding excessive processing overhead on less critical data paths while maintaining data correspondence where it matters most.
